The foll owing media characteristics affect print quality and reliability. Consider these characteristics when
evaluating new media stock.
Weight
The printer can automa ti cally feed media weights from 60 to 176 g/m
lighter than 60 g/m

90 g/m
g/m
Curl
Curl is the tendency for media to curl at its edges. Excessive curl can cause media feeding problems. Curl can
occur after the med ia passes through the printer, where it is expos ed to hi gh temperatures. Stori ng media
unwrapped in hot, hum id, cold, or dry conditions, even in the trays, can contribute to media curling prior to
printing and can cause feeding problems.

Smoothness
Media smoothne ss directly affec ts print quality. If media is too rough, toner cannot fuse to it properly. If media is
too smooth, it can cause media fee din g or print qual ity issues . Alw a ys u se media bet wee n 100 and 300 Shef fiel d
points; however, smoothness between 150 and 200 Sheffield points produces the best print quality.
Moisture content
The amount of moisture in media affects both print quality and the ability of t he prin ter to feed the media
correctly. Leave medi a in i ts original wr apper u ntil it is t ime to us e i t. Thi s limit s the e xp osur e of medi a to mo isture
changes that can degrade its performance.
Condition medi a before printing by storing it in its original wrapper in the same environment as the printer for 24
to 48 hours before printing. Extend the time several days if the storage or transportation environmen t is very
different from the printer environment. Thick media ma y also require a longer conditioning period.
Grain direction
Grain refers to the alignment of the medi a fi bers in a sheet of media. Grain is eith er grain long, running the
length of the media, or grain short, running the width of the media. For 60 to 90 g/m
use grain long fibers.
Fiber content
Most high-quality xerographic media is made from 100% chemically treated pul ped wood. This content provides
the media with a high deg re e of stabi lity re sulti ng in f e wer media f eedi ng prob lem s and bett er print qual ity. Media
containing fibers such as cotton possesses characteristics that can negatively affect media handling.

Unacce p tab l e media
The foll owing media types are not recommended for use with the printer:
•Chemically treated media used to make copies without carbon paper, also known as carbonless papers,
carbonless copy paper (CCP), or no carbon required (NCR) paper
•Preprinted media with chemicals that may contaminate the printer
•Preprinted media that can be affected by the temperature in the printer fuser
•Preprinted media that requires a regis tr ation (the precise print location on the page) greater than ±2.3 mm
(±0.09 in.), such as optical character recognition (OCR) forms
In some cases, registration can be adjusted with a program to successfully print on these forms.
•Coated media (eras able bond), synthetic media, thermal media
•Rough-edged, rough, or heavily te xtured surface med ia, or curled m edia
•Recycled media containing more than 25% post-consumer waste that does not meet DIN19 309
•Media weighing l ess than 60 g/m
2
(16 lb)
•Multiple -p a rt forms or do c uments
Selecting media
Using appropriate media prevents jams and helps ensure trouble-free printing.
To help avoid jams and poor print quality:
•Always use new, undam aged media.
•Before lo ading medi a, know t he re commended print side of the media. This information is usual ly indicat ed
on the media package.
•Do not use media that has been cut or trim m ed by hand.
•Do not mix media sizes , types, or weights i n the same source; mixing result s in j am s.
•Do not use coated media unl ess they are specifical ly designed for elect rophotographi c prin ti ng.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
•Use grain long papers for best results for 60 to 90 g/m
2
weights.
•Use only for m s and letterhead printed using an offset lithographic or engraved printing process.
•Av oid papers with rough or heavi ly textured surfaces.
Use papers printed with heat -resistant inks designed for use in xerographic copiers. The ink must be able to
withstand tempe ratures up to 180°C (356°F) without me lt ing or releasing hazardous emissions. Use inks that
are not affected b y the resin in toner. Inks that are o xidation-set or oil-based generally meet these requirements;
latex inks might not. When in doubt, contact the paper supplier.
Preprinted papers such as letterhead must be abl e to wi thstand temperatures up to 180°C (356°F) without
melting or releasing hazardous emissions.

Using letterhead
Check with the man ufacturer or vendor to determine whether the chosen preprinted letterhead is acceptable for
laser printers.
Page orientation is important when printing on letter head. Use the followi ng table for help when lo ading

Using tran sparencies
Print samples on the transparencies being considered for use before buying large quantities.
When printing on transparencies:
•Fr om MarkVisi on™ Professional , th e print er software, or the control panel, set the Pap er Type to
Transparency.
•Feed transparencies from the standard tray (Tray 1) or the multipurpose feeder.
•Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to
ensure transparencies are able to withstand temperatures up to 180°C (356°F) without melting,
discoloring, offsetting, or releasing hazardous emissions .
•Use transparencies that are 0.12–0.14 mm (4.8–5.4 mil) in thicknes s or 161–179 g/m
2
in weight.
•Print quality and dur ability depend on the transparencies used.
•To prevent print quality problems, avoid getting fingerprints on t he transparencies.
•Before loading transparencies, fan the stack to prevent sheets from sticking together.
•We recommend Lexmark part number 12A8240 for let ter-size and Lexm ark part numbe r 12A8241 for
A4-size transparencies.
Using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
•
When printing on envelopes:
•Fr om the control panel, set the Paper Source based on the source in use. From the control panel, the
printer so ft ware, or Mark Vision Professional, set t he Paper Type to Envelope, and select t he envelope size.
•Use env elopes designed specific all y for laser print ers. Check with the manufacturer or vendor to ensure
the envelopes can withstand temper atures up to 180°C (356°F) without sealing, wrinkling, curling
exces sively, or rele asing hazardous emissio ns.
•For the bes t performance, us e en vel opes made from 90 g/ m

exceed 90 g/m
